Use our free vocabulary trainer to create personal word lists and improve your vocabulary. We use a two-way synchronization method, which means you can access all your word lists on your mobile devices or on your desktop, all you need is a free account.

Wish we could save words from mobile app

Leo is my go-to German dictionary that I use all the time, as the translations and further context etc seems the best of all translations I have tried.

The web version also has a great feature - if you create an account then any word you look up you can "save" and it will be added to your account to be reviewed in flashcards later, including on your iPhone. However, there is no option to save words when you look at them on the iPhone app - which is where I use Leo 95% of the time.

I would gladly pay for this feature (and to lose the adverts). Seems odd that they have the feature elsewhere but not in the iPhone app. I can't even get it to work if I just use the mobile version of the website. Shame. That's the only reason I don't give this app 5*.

Number one dictionary

My favourite dictionary app. Fast and reliable.

Used to be better with more grammatical information. Too simplistic now

Developer Response ,

We've actually added more grammatical information (this doesn't require an APP update) and will continue to do so. If you're missing a specific information, please drop us an e-mail at
